- RADIATOR.

Application filed August 1, 1924. Serial No. 729,522.

This invention relates to improvements in radiators and more especially light gauge metal radiators, and aims to provide improvements therein. 1 i

In the construction of these light gauge metal radiators, sheet metal has commonly been used, one or more pieces of the sheet metal being used to form a section. Seams of considerable length are required to unite the meeting edges of the sheet metal forming each section, and the produc tion of an enduring leak-tight seam has been either unsatisfactory or costly. I

The present invention provides a radiator simulating the shape and form of the usual house-heating radiator, which is practically seamless, being formedof tube-stock, and which in thin gauge metal and substantially without seams, avoids the objection to seams encountered in radiatorsformed of light gauge sheet metal.

An embodiment of the, invention'is illusti'atediiu the accompanying drawings, in which i Fig. 1 is a side elevation, (with section) of said embodiment.

i 2 is an end elevation thereof.

Fig. 3 is a top plan view (with parts in section).

Figs. 4 and 5 are detail views. 4

Referring to said drawing, numeral 10 designates a tube, conveniently of light gauge sheet metal, such as 20' B. & S. gauge or even lighter, which is. bent into the form of a coil 12 comprising a plurality of complete bends or sections 14. Each complete bend or section comprises two vertical legs 16, 17 and top and bottom portions 19 and 20. The legs 16 and 17 and the top portion 19 of each bend orsection 14 are preferably non-spiral, thelegsbeing'straight up and down and the top portion 19 straight across from one leg to the other. The pitch or cross-over from onebend or section 14 to another is preferably through thebottom portion 20 of each bend (or commonto two bends) which is arranged diagonally. The cross-over could obviously be at the top instead of at the bottom, as shown and described.

The legs 16, 17 are preferably flattened as indicated at 24' in such manner that the flattened faces of each bend or section are opposite one another; thereby providing for p arts in or sheets of a good circulation of air between the radiator sections.

The bends or sections 14 are also prefer ably connected otherwise than through the i cross-over bottom portion 20, for the purpose of rigidity, and are also preferably laterally connected in suclrmannerthat the interiors of the sections are in additional communication, for the purpose of better circulation or distribution of the heating fluid therein. To this end, the top and bottom portions 19 and 20 may be connected by short tubes or nipples 25, 26. Thetop and bottom portions 19 and20 have openings 27, 28, 29, 30, for receiving the ends of the nipples 2-5, 26, and for convenience in manufacture the sides of the top and bottom por' tions immediately around said openings 27, 28, 29., 30, are flattened, as indicated at 33, 34. There is preferably a screw-threaded connection between the nipples 25, 26 .and the sections 14, and as the metal of thesections 14 is or may be too thin for the formation of adequate screw-threads therein, the

openings 27, 28, 29, 30 are preferably bushed or rimmed with a heavier ring of metal 37 which is fastened thereto by. seaming or crimping, as indicated in Fig. 5, and threads 38 are formed in the ring 37. i

The ends 40, 41 of the tube 10, are closed in suitable manner. The ends are preferably flattened so that the edge portions lie together, and the length of the edges being short it is neither difficult norexpensive to close the ends by practically any usual means. The preferredv means is a strip of relatively heavy metal45, which is seamedor crimped on the ends 40, 41,. as indicated in Fig. 4. Such a joint will be durable, and not affected by strains,shocks, etc., to which the radiators may be subjected, as is the case withlong seams, as for example those in sheet metalradiators.

Method-According to the present method 5 apiece of tube stock 10, preferably oflight gauge metal, and of sufficient length to form a plurality ofcomplete bends, or sections,

is take-n and bentinto the'form of a coil 12 shown as the bottom portion 20, diagonally. The top or bottom portions 19, 20 or both are provided with openings 27, 28, .29, 30, and one section is joined to another by nipples 25, 26 for example. The parts of the tube portions 19, 20 in which the openings are formed are preferably formed with flat portions 33, 34. The ends 40, 41 of the tube 10 are closed in suitable manner, as by clamping between the edges of a strip of metal The adjacent sides of the leg portions 16, 17 are preferably flattened, as indiated at 2%.

Modifications of the construction herein specifically illustrated and described may be made without departing from the idea of invention. Variations in the mode of procedure specifically described may be made without departing from the invention.

What is claimed is:

1. A radiator comprising a plurality of tubular sections or bends formed from tubular stock, means placing said sections in series conennunication, and means placing said sections in lateral communication.

2. A radiator comprising sections each comprising a tube bent to 7 form tubular U-shaped portions having vertical legs and a cross tubular portion connecting a leg in each of two adjacent U-shaped portions.

3. A radiator comprising sections each comprising :a tube bent to form tubular U- shaped portions, and a cross tubular portion connecting a leg in each of two adjacent U-shaped portions, and means connecting adjacent sections for communication at the rend opposite said cross-portion.

4. A radiator comprising a tube bent into a coil comprising a plurality of complete turns or bends, and having lateral means of communication between adjacent bends, said bends being flattened crosswise of the coil.

A radiator, comprising a tube bent in the form of a coil, each complete bend comprising two vertical non-spiral legs and top and bottom portions one of said portions connecting said legs, and the other portion of which runs diagonally and connects one complete bend with another.

'6. A radiator, comprising a tube bent in. the "form of a coil, each complete bend comprising two vertical non-spiral legs and top and bottom portions one of said portions connecting said legs, and the other portion of which runs diagonally and connects one complete bend with another, said legs being flattened.

7. A radiator, comprising a tube bent in the form of :a coil, each complete bend com prising two vertical non-spiral legs and top and bottom portions one of said portions connecting said legs, and the other portion of which runs diagonally and connects one complete bend with another, and means connecting the complete bends at top and bottom.

8. A radiator, comprising'a tube bent in the term of a coil, each complete bend comprising two vertical non-spiral legs and top and bottom portions one of said portions connecting said legs, and the other portion of which runs diagonally and connects one complete bend with another, and means connecting the complete bends at top and bottom, said means comprising short tubes or nipples fitting openingsin said bends.

A radiator, comprising a tube bent in the form of a coil, each complete bend comprising two vertical non-spiral legs and top and bottom portions one of said portions connecting said legs, and the other portion of which runs diagonally and connects one complete bend with another, and means connectingthe complete bends at top and bottom, said means comprising short tubes or nipples fitting openings in said bends, said diagonal portion of the bend having a portion in plane at right angles to the axis of the coil.

10. A radiator, comprising a tube bent in the form of a coil, each complete bend comprising two vertical non-spiral legs and top and bottom portions one of said portions connecting said legs, and the other portion of which runs diagonally and connects one bend with another, and means connecting the complete bends at top and bottom comprising short tubes or nipples fitting openings in said bends, said legs being flattened.
